Effect of simultaneous cyclic variation of stress and temperature on a high temperature material
For the purpose of showing experimentally, by laboratory tests, if a certain high temperature material is suitable for turbine blades in gas turbine engines, it has so far been customary to adopt creep tests and also, occasionally, fatigue tests at high temperatures. Thus, Toolin and Mochel , for example, have carried out extensive bending fatigue tests on a great number of high temperature alloys at 1,200 and 1,500° F (650 and 815° C).
